Algal Polysaccharides: Properties and Applications
Bioactive polymers mainly polysaccharides such as cellulose, chitin, amylose and beta-glucan are well discovered from various sources in nature. Amongst chitin, as the second most abundant polysaccharides after cellulose, is known as a highly insoluble polysaccharide consisting of β-4-linked N-acetyl-D-glucosamine, which has been identified as a structural component of crustaceans, crabs, shrim...
متن کاملcontrol of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Both hyperglycaemia and hyperlipidaemia are major risk factors for the development of coronary artery diseases and atherosclerosis, and therefore therapeutic drugs must be developed for treatment of them. Pumpkin polysaccharides (PPs) are biomacromolecules with varying bioactivities. In this study, PPs were extracted with commercial thermostable α-amylase, and their hypolipidaemic and hypoglyca...
متن کاملHydrodynamic properties of connective-tissue polysaccharides.
The major hydrodynamic properties of the connective-tissue polysaccharides are those that describe polysaccharide-water interaction as embodied in their osmotic-pressure and hydraulic-conductivity properties. This study shows that, for polysaccharides such as chondroitin sulphate, hyaluronate and the heparin-like polysaccharides, their hydrodynamic properties depend primarily on the presence of...
متن کاملSome Physicochemical Properties of Specific Polysaccharides*
In recent years the study of immunologically specific polysaccharides has not only contributed to the understanding of bacterial specificity (1) but has also proved of purely chemical interest because of the unusual structure of certain members of the group. Thus the specific polysaccharide of Type III pneumococcus has been shown to be a polyaldobionic acid built up of glycurono-glucose units (...
